To all whom t may concern:

Be it known that we, NILIJAM J. MILLER and DAVID W. JONES, citizens of the United States, residing zat-Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Explosion-Engines, of which the following is a specification.

Our invention relates to improvements in explosion engines and has especial reference to the construction of a valve therefor; our valve is adapted to provide both inlet and exhaust for one cylinder or a plurality of cylinders, and is articularly adapted for use with two cylinders, although its adapta- .tion to four cylinders is readily accom-y plished. Our improved valve admits the charge longitudinally thereof through an opening approximately at the central point of the circumference of the valve into the cylinder, and the exhaust gases are adapted to be admitted into a longitudinal passageway in the valve and they are exhausted out through the end thereof; the exhaust passage is partially surrounded by the inner end of the intake passage or 'chamber and the walls are thereby somewhat cooled. Our valvel is intended primarily to loe-rotated, and a device for this purpose is shown in the drawings. The valve is particularly adapted for use with four-cycle engines.

The description of the parts and their combinations will hereinafter be set forth in detail. i In the drawings which are hereto attached and hereby made a part of this specification, Figure l shows a vertical transverse section through the cylinders and the valve in place; F ig. 2 shows a longitudinal section through the valve and the actuating means therefor.

Referring to ythe drawings., l indicates a,

cylinder of an explosion engine, 2 indicates a companion cylinder, and it may be here stated that our valve is primarily adapted for use with two cylinders, although its use is not confined to such construction; 3 is the piston ain cylinder l, and a similar piston 3 is adapted for actuation in cylinder 2. The valve et is preferably mounted in ball bearings 5 to rotate freely. being actuated through the gearing shown at (3; thc intake passage 7 is comparatively long and the explosive mixture is admitted thereto through the tube 8. Packing rings arc shown at 9, and the gear 10 mounted on the intake vchamber or portion of the valve meshes with the gear 6 for the purpose of giving the valve a rotary movement. The explosive mixture enterin through passageway 7 lon'- gitudinally of te valve strikes the walls ll and l2 which form the inner end of the. intake passageway and the mixture is thereby directed through the passageway 13 into the explosion chamber of the cylinder.

The timing of the parts being appropriately performed, the explosion will take place and the exhaust gases will thereupon rush outwardly through the passageway 14 into the exhaust passageway l5 and thence into the tube 16 into the outer atmosphere if desired. It will be noted that the walls l1 and l2 forming the inner end of the intake compartment or chamber, projectnecessarily into the path of the discharge of the exhaust gases, and are thereby heated; the incoming charge, coming into contact with these walls, exercises a cooling effect thereon, and kee s the valve constantly in good working or er. -Further, the intake and exhaust compartments or passageways through the valve are entirely distinct and separate, which is of importance and which is accomplished by admitting the explosive mixture longitudinally through one end of the valve land exhausting the burnt gases longitudinally through the opposite end of the valve. This valve is seen to be hollow with a parti tion therein, the ends of the valve being open to communicate with the hollow interior; there are no end walls, and this construction permits Afree and unobstructed inflow of the combustible mixture and outflow of the exhaust gases. The exhaust does not therefore come into contact with the intake end of the valve, but is confined entirely to the portion of the valve beyond the middle thereof; this makes the valve construction simple and the bearings at the exhaust end only are in danger of heating. The bearings for the intake end of the valve are not subjected to the heat of the exhaust and therefore the problem of mounting the valve is rendered easy. It is seen that the intake and the exhaust are not carried on sidc by side except in the region of the partition, and this is peculiarly constructed in a manner hereinafter specially described for the purpose of directing the cooling incomingr charge against the partition walls which are heated by the exhaust.

etA

main exhaust passage Way 15, and so out vthrough pipe 16.

` charge is directed over acomparativelyy large surface heated by the exhaust gases,l

y. The partition walls.f 11 and 12 are arran ed transversely of the valve as appears in ig..

2, and the partition thus formed is angular in outline, whereby the cool incoming whereby the I walls are beneficially cooled and the exhaust therefore is deprived of some of its lheat before passing the region of the bearings. vThis transverseangular parv ltition wall has advantages which a longitu dinal Wall does noty possess, in ythat it eec. tually confines the exhaust at one end of the valve and theA intake to the opposite end of the' Valve, and makes the valve simpler in construction. In this construction of valve, a supply of combustible mixture is always ready to be provided to the cylinders,

and the exhaust lows'with regularity anduniformity, and the operation of the'engine is thereby rendered harmonious and highlyl efficient. lAs seen the valve ports through which the intake 1s introduced into thecylinder are'distinctpfrom those by which the exhaust is permitted to escape, so thatwe avoid the loss of combustible mixture arising from usingv the same'port for both purposes; further, the arrangement of the passage'ways within the valve is 'such that the incoming charge exercises a cooling effect upon the'walls of the exhaust passageway, thereby adding to the ease ooperation and the efficiency of the valve. Further, the construction of this valvev is such that it is peculiarly adapted for use with two cylinders, supplying thesame with charges at appropriate intervals and conducting the exhaust therefrom with certainty and `regularity. We are aware that rotary valves are in use, 'but donot know of any valve which is constructed to admit the charge andto per` mit the escape of the exhaust in a manner in which we accomplish these functions, and at the same time adapting the valve toa plurality of cylinders. Vle are aware that a series of va1ves have been provided for a series ofcylinders, but we'do not clairnsuch constructions. i

' We do not limit ourselves to the specitic vconstruction 'herein set forth,` but desireto claimany modifications which lie within the scope of our invention.

-What We claim is:

In an explosion engine, a cylinder., arotary valve thereon having open ends and a longitudinal intake passage Way communicating v with one end, and a longitudinal exhaust f passage-,way communicating with the other end, a partition comp-rising converging walls interposed vtransversely in said valve between the inner ends of said passageways and projecting into said exhaust passage Way, said'valve having a plurality of `open ings affording communication between said cylinder and said intake passage way, and a plurality of openings affording communication between said cylinder and saidexhaust passage way.

In testimony whereof we aiiix our signa-s tures in the presence of two' witnesses.
